Genetic evidence supports demic diffusion of Han culture
The spread of culture and language in human populations is explained by two alternative models: the demic diffusion model, which involves mass movement of people; and the cultural diffusion model,Expand

Temporal precision in the neural code and the timescales of natural vision
The timing of action potentials relative to sensory stimuli can be precise down to milliseconds in the visual system, even though the relevant timescales of natural vision are much slower. Expand

Analyses of genetic structure of Tibeto-Burman populations reveals sex-biased admixture in southern Tibeto-Burmans.
An unequal contribution of male and female lineages from parental populations to admixed ones is not uncommon in the American continents, as a consequence of directional gene flow from European menExpand

Population receptive fields of ON and OFF thalamic inputs to an orientation column in visual cortex
The primary visual cortex of primates and carnivores is organized into columns of neurons with similar preferences for stimulus orientation, but the developmental origin and function of thisExpand

Neuronal nonlinearity explains greater visual spatial resolution for darks than lights
Significance Light and dark stimuli are separately processed by ON and OFF channels in retina and thalamus. Although most textbooks assume that ON and OFF visual responses are relatively balancedExpand

Temporal Precision in the Visual Pathway through the Interplay of Excitation and Stimulus-Driven Suppression
Visual neurons can respond with extremely precise temporal patterning to visual stimuli that change on much slower time scales. Here, we investigate how the precise timing of cat thalamic spikeExpand

Neuronal and Perceptual Differences in the Temporal Processing of Darks and Lights
Visual information is mediated by two major thalamic pathways that signal light decrements (OFF) and increments (ON) in visual scenes, the OFF pathway being faster than the ON. Here, we demonstrateExpand

Visual Orientation and Directional Selectivity through Thalamic Synchrony
Thalamic neurons respond to visual scenes by generating synchronous spike trains on the timescale of 10–20 ms that are very effective at driving cortical targets. Here we demonstrate that thisExpand

Generating high gray-level resolution monochrome displays with conventional computer graphics cards and color monitors
We show how to achieve a white display by adding video amplifiers to duplicate the monochrome signal to drive all three guns of any color monitor. Expand
